- Worth noticing
- Its refund example records a refusal when an amount exceeds a stated ceiling, then demonstrates detection after one byte on disk is changed.
Field notes
The examples show both framework adapters and function-level instrumentation, including a refund policy that refuses amounts over its ceiling. A sample run writes records to a local stream, exposes them through CLI commands, and checks the chain against a pinned fingerprint. The site also lists Cloudflare R2 and MinIO storage; AWS S3 is marked as in progress rather than available.
